"Biological reward comes from the release of the neurotransmitter, dopamine. Dopamine release is promoted by performing working memory tasks, which suggests that working memory tasks are actually rewarding. In the study of human subjects by Fiona McNab and colleagues in Stockholm, human males (age 20-28) were trained for 35 minutes per day for five weeks on working memory tasks with a difficulty level close to their individual capacity limit. After such training, all subjects showed increased working memory capacity. Functional MRI scans also showed that the memory training increased the cerebral cortex density of dopamine D1 receptors, the receptor subtype that mediates feelings of euphoria and reward.
czy to może działać ? chyba zrobię mały reaserach na ten temat ( tak w ciągu dwoch tygodni i wkleję go na forum)

1. a) "Ritalin boosts learning by increasing brain plasticity"http://phys.org/news187187471.html
1. b) "Methylphenidate amplifies long-term plasticity in the hippocampus via noradrenergic mechanisms" http://learnmem.cshlp.org/content/15/8/580.full
"Previously, improvements were considered a by-product of increased attention; however, we hypothesize that methylphenidate directly alters mechanisms underlying learning and memory, and therefore examined its effects on hippocampal long-term potentiation and long-term depression."
2. A co z Modafinil'em ? Próbowaliście ?
3. Mam nadzieję, że nie zaśmiecam wątku, jeszcze tylko dodam, że trening pamięci roboczej to nie pierdułka, "Workig memory training decreases hippocampal neurogenesis" http://www.safar.pitt.edu/content/grant ... 0Kline.pdf
obniża neurogenez, gdyż taki trening, to nie niewinna zabawa, tylko poważny stressor dla mózgu :) Czyli moja linia rozumowania w obecnej chwili wyglada następująco : taki trening trochę szkodzi, więc musi działać
4.Trochę o skutkach ubocznych :http://www.amphetamines.com/adhd/drugsbrain.html
"Basically, that paper shows that methylphenidate actually attenuated the deficits associated with damage induced by methamphetamine
(methamphetamine does all the damage of amphetamine , but adds A LOT to that damage). So surprisingly enough, methylphenidate actually can attenuate the neurotoxicity associated with amphetamine, if taken along with it." http://www.quora.com/What-are-the-long- ... italin-use

"have now demonstrated that methylphenidate and amphetamine can cause lasting changes to those areas of the developing brain where dopamine receptors are found. The disrupting effects appear to be centered on the nucleus accumbens" z innej beczki : "
In addition, in July 2007, researcher Jon-Kar Zubieta published findings that the nucleus accumbens is central to the machinery of the placebo effect. His group has confirmed that specific neural circuits and neurotransmitter systems respond to the expectation of benefit during placebo administration and that these expectations induce measurable physiological changes."Czy można brać równocześnie amf i metylo ?
